Technical field
The invention belongs to hydrodynamic drive technical field, particularly relate to a kind of hydraulic transmission oil with excellent abrasion resistance.
Background technology
Hydrodynamic drive is working medium with liquid, utilizes liquid kinetic energy to carry out the Fluid-transmission of transferring energy.Fluid-flywheel clutch, fluid torque-converter and automatic transmission etc. are all typical hydraulic transmission systems.
Impeller is that rotating speed, the moment inputted by engine (oil engine, electric motor, turbine etc.) is changed, through the working portion of output shaft band movement machine.Hydraulic transmission oil and each impeller be contained on input shaft, output shaft, housing interact, and produce the change of the momentum moment, thus reach the object of transferring energy.Hydrodynamic drive has very big difference with the hydrostatic transmission that can carry out transferring energy by liquid pressure on principle, stuctures and properties.Be only that working medium contacts by liquid between the input shaft of hydrodynamic drive and output shaft, directly not contacting between component, is a kind of non-rigid transmission.The advantage of hydrodynamic drive is: can absorb shock and vibration, and overload protection is good, and even when output shaft blocks, engine still can operate and injury-free, and band load is started easily, can realize automatic transmission and stepless speed regulation etc.Therefore hydrodynamic drive can improve the dynamic performance of whole transmission mechanism.
Hydraulic transmission oil not only transmits power as working medium, and can also be used for lubricating bearings and gear, and the resistance to abrasion that hydraulic transmission oil is good, can ensure that the hydrodynamic drive parts of various unlike material are not easily worn in the operating condition.
But, existing hydraulic transmission oil makes improvements mainly for hydrodynamic drive oil viscosity, have ignored its resistance to abrasion, such as, State Intellectual property right document discloses a kind of hydraulic transmission oil, and { application number: 201410548674.5} comprises the component of following massfraction: synthetic ester: 50 ~ 90%; Additive: 3.5 ~ 11%; Surplus is polyalkylene glycol.Hydraulic transmission oil provided by the invention is oil based on synthetic ester and polyalkylene glycol are prepared in certain proportion, auxiliary with additive, the hydraulic transmission oil obtained can keep lower viscosity at low temperature, start smoothly at low temperatures with guarantee equipment, have ideal low-temperature performance, pour point can be low to moderate-60 DEG C, at high temperature can keep higher viscosity, maintain certain oil film thickness, to ensure the lubrication of equipment, meet the operation of vehicle under various severe rugged environment completely.
Although aforesaid method improves the viscosity index of hydraulic transmission oil, its abrasion resistance is poor, the better protection that cannot provide for equipment.
